Hawle flush valve
The operating waterworks „DeWatergroep“ detected an inaccuracy of the water meters. The reason for the deviations of the water meters was contamination due to oversizing of the pipe network and stagnant water in stub lines. The construction of a ring line would have been one way of solving this problem, but a costly one.
The decision was made to use a Hawle flush valve in search of cheaper alternative solutions to remove suspended solids from the network. This is placed at the end of the branch line, so that the water pipe can be flushed and the suspended particles can be easily removed from the pipe network.
